Bug#247538: sshd: logout not recorded in utmp



Package: ssh
Version: 1:3.8p1-3
Severity: important

When ssh creates a tty with a number greater than 999, it does not
remove it correctly from utmp. The problem is that ssh uses at one place
a 8-chars buffer while everywhere else it uses larger buffers: since
"pts/1234\0" is more than 8 chars long, it is truncated.

The problem shows probably on *very* loaded login servers, but it shows
also on 2.6.4+ kernels, where the tty numbers are never reused.

If the line

	char line[8];

in loginrec.c:1357 becomes

	char line[UT_LINESIZE];

that fixes the problem.
